摘要:
AbstractA mapping finite element method is proposed for the solution of elastic problems in two‐dimensions. This method, based on the logarithmic condensation of physical space, is found to give significantly greater accuracy than when the problem is solved in the physical plane using the standard FEM. Logarithmic condensation of space also permits the solution of large aspect‐ratio problems of this type, accurately and economica
